[testcase] madvise->semaphore deadlock 2.4.0

2001-01-09 Thread Mike Galbraith
Greetings, While trying to configure ftpsearch, the process hangs while running it's madvise confidence test below. It appears to be taking a fault in madvise_fixup_middle():atomic_add(2, &vma->vm_file->f_count) and immediately deadlocking forever on mm->mmap_sem per IKD. (Virgin 2.4.0 agrees)
